How hard is the water in Lincoln County, KS?

34.5 grains per gallon

The median hardness measured in Lincoln County, KS is 590 mg/L as calcium carbonate, which is 34.5 gpg. That is very hard on the USGS scale. It comes from 297 samples at 11 sites between 1990 and 2016, drawn from every sampling site in the county, wells and surface water together.

How much it varies here

Half the sites came in between 30.8 and 37.2 gpg. The whole middle of that range gives the same answer, so a test of your own tap is unlikely to change it. Confidence in the county figure: high (how it is measured).

What to do next

At 34.5 gpg a softener pays its way here. Before you buy, check the quoted unit's grain capacity against the sizing table below, and ask whether it regenerates on demand, which uses less salt than a timer. Call your utility for its own report if you are on city water.

From 25.7 to 42.6 gpg

The softest single sample on record in Lincoln County was 440 mg/L and the hardest 730 mg/L, a 2-fold gap. The top quarter of sites read above 37.2 gpg and the bottom quarter below 30.8 gpg.

What a softener would cost to run

For a household of 3, a 48,000-grain unit covers a week between regenerations. Expect about 753 lb of salt a year (19 bags of 40 lb, about $135), and roughly 2,346 gallons of regeneration water. Installed, most units run $1,000 to $4,500; spread over 15 years with salt, that is about $235 a year.
